I just got a ACT street flywheel and the mechanic thats fixing my car only wants to put in a dual mass flywheel. For anyone that has that flywheel what are the major differences and does it really change the whole setup that much. I understand there will be some more noise, but he's saying that its going to tear up my transmission after 5k miles or sooner. Any thoughts on this will be greatly appreciated.

 

The mechanic is an idiot.
